Description

For demanding measurement tasks

The model LH-10 submersible pressure transmitter has been designed for level measurement in contact with the medium

in harsh operating conditions. It oers an accuracy of 0.25 %

and, with an ingress protection of IP 68, is suitable for permanent level measurements up to 984 ft. (300 m) water column.

It oers excellent quality, is reliable and, through a multitude

of options, can be used in all conventional level measurement applications. For instance, integrated temperature measurement, lightning protection, a Hastelloy cable are available as options.

Robust and reliable

A hermetically-sealed, fully-welded and exceptionally robust

stainless steel case ensures a long service life and permanent sealing.

Specically for external applications, integrated lightning protection is available, in order to ensure a maximum

operating life in harsh environments.

For the highest media resistance, this submersible pressure transmitter is available in an optional design out of Hastelloy and high-resistance FEP cable.

For the highest accuracy requirements, the optional tempera-

ture measurement enables the compensation of temperature

uctuations in the medium on the measuring result.

Description Order number

Cable strain relief clamp

The cable strain relief clamp enables easy and secure mechanical fastening of the submersible pressure transmitter's cable at the measuring point. It acts as a guide for the cable, in order to avoid mechanical damage and to reduce the tensile stress.

Additional weight

The additional weight increases the dead weight of the submersible pressure transmitter.

It simplies the lowering into monitoring wells, narrow shafts and deep wells. It eectively reduces negative environmental inuences on the measuring result from the measured medium (e.g. turbulent ow).

Stainless steel 316L, approx. 500 g, length (L) 130 mm

Terminal box

The terminal box, with IP 67 ingress protection and watertight ventilation element, provides

a moisture-free electrical termination for the submersible pressure transmitter. It should be mounted in dry environment or directly in the switch cabinet.

Filter element

The lter element prevents dirt and moisture from entering the venting tube. The watertight diaphragm also oers a reliable protection for the submersible pressure transmitter.
